In step S410, the CPU 201 determines whether or not an instruction to stop the moving image recording mode has been issued.
For example, when the power switch is ON and the operation mode other than the moving image recording mode is selected by the mode selection switch, the CPU 201 determines that the stop of the moving image recording mode is instructed. For example, when the power switch is turned off, the CPU 111 determines that the stop of the moving image recording mode is instructed. When the stop of the moving image recording mode is instructed, the CPU 201 proceeds from step S410 to step S411 (YES in step S410).
For example, when the power switch is ON and the moving image recording mode is selected by the mode selection switch, the CPU 201 determines that the stop of the moving image recording mode has not been instructed. When the stop of the moving image recording mode is not instructed, the CPU 201 returns from step S410 to step S403 (NO in step S410).

In step S411, the CPU 210 transmits a reception stop command to each of the communication unit A201 and the communication unit B202.
Receiving the reception stop command, the communication unit A 201 stops the process of receiving each RAW image data and their additional information transmitted from the communication unit A 108 via the cable 300.
Receiving the reception stop command, the communication unit B202 stops the process of receiving each RAW image data and their additional information transmitted from the communication unit B109 via the cable 301.
When the reception stop command is transmitted to each of the communication unit A201 and the communication unit B202, the CPU 210 ends the moving image recording process C1.

  Next, the moving image data merging process D1 performed by the external device 200 according to the first embodiment of the present invention will be described with reference to FIG. FIG. 5 is a flowchart for explaining the moving image data merging process D1 performed by the external device 200 according to the first embodiment of the present invention. The CPU 210 can control the moving image data merging process D1 by executing the program Pg4 stored in the memory C209.

In step S501, the CPU 201 determines whether the start of the moving image data merging mode is instructed. The moving image data merging mode is one of a plurality of operation modes that the external device 200 has.
For example, when the moving image data merge mode is selected by the mode selection switch when the power switch is ON, the CPU 201 determines that the start of the moving image data merge mode has been instructed. When the start of the moving image data merging mode is instructed, the CPU 201 proceeds from step S501 to step S502 (YES in step S501).
For example, even if the power switch is ON, if the moving image data merge mode is not selected by the mode selection switch, the CPU 201 determines that the start of the moving image data merge mode has not been instructed. When the start of the moving image data merging mode is not instructed, the CPU 201 repeats step S501 (NO in step S501).

In step S <b> 502, the CPU 201 transmits an index display start command to the display control unit 206. Upon receiving the index display start command, the display control unit 206 displays a reduced image (also referred to as a representative image or a thumbnail image) corresponding to each moving image data recorded in the storage device 205 so as to be displayed on the display device 207. A process for controlling the device 207 is started. For example, the display control unit 206 controls the display device 207 so that four, six, or eight reduced images are displayed simultaneously. In addition, the display control unit 206 controls the display device 207 so that, for example, the reduced image corresponding to each moving image data is scroll-displayed for every four, six, or eight reduced images. The user can select a reduced image corresponding to moving image data to be reproduced by operating the cross button.
When the index display start command is transmitted to the display control unit 206, the CPU 201 proceeds from step S502 to step S503.

In step S503, the CPU 201 determines whether or not the start of the merge process has been instructed in a state where one reduced image is selected.
For example, when one set image is selected and the set button is pressed, it is determined that the start of the merge process has been instructed. When the start of the merge process is instructed, the CPU 201 proceeds from step S503 to step S504 (YES in step S503).
For example, when one reduced image is selected and the set button is not pressed, it is determined that the start of the merge process has not been instructed. When the start of the merging process is not instructed, the CPU 201 repeats step S503 (YES in step S503).

In step S <b> 504, the CPU 201 transmits a moving image data search command to the recording control unit 204. The moving image data search command includes ID information of moving image data corresponding to the reduced image selected by the user when the start of the merge process is instructed. Hereinafter, the moving image data corresponding to the reduced image selected by the user when the start of the merging process is instructed is referred to as “moving image data mv3”. The recording control unit 204 that has received the moving image data search command starts a process of searching the storage device 205 for moving image data having the same ID information as the ID information of the moving image data mv3 included in the moving image data search command. Hereinafter, the moving image data having the same ID information as the moving image data mv3 is referred to as “moving image data mv4”. Whether the moving image data mv4 exists in the storage device 104 is notified from the recording control unit 204 to the CPU 201.
When the moving image data mv4 exists in the storage device 205, the CPU 201 proceeds from step S504 to step S505 (YES in step S504).
When the moving image data mv4 does not exist in the storage device 205, the CPU 201 proceeds from step S504 to step S507 (NO in step S504).

  In step S <b> 505, the CPU 201 transmits a moving image data merge command to the recording control unit 204. In the moving image data merging command, each RAW image data included in the moving image data mv3 and each RAW image data included in the moving image data mv4 are rearranged according to their time code information, and the moving image data mv3 and mv4 are converted into one moving image data. Start the process of merging. For example, when the frame rate of the moving image data mv3 and mv4 is 30 frames / second, the frame rate of the combined moving image data is 60 frames / second. Then, the recording control unit 204 records the merged moving image data in the storage device 205. However, when there are two or more RAW image data having the same time code information in the merged video data, the recording control unit 204 records only one of them in the storage device 205 and stores the rest in the storage device 205. Do not record. Thereby, it is possible to prevent duplicate RAW image data from being recorded in the storage device 205. The recording control unit 204 determines which RAW image data of two or more RAW image data having the same time code information is recorded in the storage device 205 based on, for example, recording designation information described later. When all the RAW image data included in the moving image data mv3 and all the RAW image data included in the moving image data mv4 are rearranged according to their time code information, if all the time code information continues, the original moving image Data will be restored.

Note that in step S505, the recording control unit 204 may divide the combined moving image data every time a portion where time code information is not continuous is detected. In step S505, the recording control unit 204 may divide the merged video data every time different ID information is detected.
Further, in step S505, the recording control unit 204 may record only one portion where the time code information of the merged moving image data continues in the storage device 205 as one or a plurality of moving image data. Further, in step S505, the recording control unit 204 may record only one portion where the ID information of the merged moving image data matches as one or a plurality of moving image data in the storage device 205.
When the moving image data merging instruction is transmitted to the recording control unit 204, the CPU 201 proceeds from step S505 to step S506.

In step S506, the CPU 201 determines whether or not the merging process in the recording control unit 204 has ended. The recording control unit 204 notifies the CPU 201 whether or not the merging process in the recording control unit 204 has ended.
When the merging process in the recording control unit 204 is completed, the CPU 201 proceeds from step S506 to step S507 (YES in step S506).
If the merging process in the recording control unit 204 has not ended, the CPU 201 repeats step S506 (NO in step S506).

In step S507, the CPU 201 determines whether or not an instruction to stop the moving image data merging mode is given.
For example, when the power switch is ON and the operation mode other than the moving image data merge mode is selected by the mode selection switch, the CPU 201 determines that the stop of the moving image data merge mode has been instructed. For example, when the power switch is turned off, the CPU 201 determines that an instruction to stop the moving image data merging mode is given. When an instruction to stop the moving image data merging mode is given, the CPU 201 ends the moving image data merging process D1 (YES in step S507).
For example, when the power switch is ON and the moving image data merge mode is selected by the mode selection switch, the CPU 201 determines that the stop of the moving image data merge mode has not been instructed. When the stop of the moving image data merging mode is not instructed, the CPU 111 returns from step S507 to step S502 (NO in step S507).

Next, an image data transmission method E21, which is an example of an image data transmission method performed between the imaging device 100 and the external device 200, will be described with reference to FIG. FIG. 8 is a diagram for explaining the image data transmission method E21.
The image data transmission method E21 is a case where the imaging unit 101 generates a plurality of RAW image data at 30 frames / second, and each of the communication unit A 107 and the communication unit B 108 outputs a plurality of RAW image data at 30 frames / second. Used when sending.
Also, in the image data transmission method E21, the frame rate of the moving image data reproduced from the storage device 104 is 30 frames / second, and each of the communication unit A 107 and the communication unit B 108 has a plurality of RAW images at 30 frames / second. Also used when sending data.

In FIG. 8, moving image data 802 is moving image data including a plurality of RAW image data supplied to the communication unit A 107 and a plurality of RAW image data supplied to the communication unit B 108. The frame rate of the moving image data 802 is 60 frames / second.
In FIG. 8, moving image data 803 is moving image data including a plurality of RAW image data transmitted from the communication unit A107. The frame rate of the moving image data 803 is 30 frames / second.
In FIG. 8, moving image data 804 is moving image data including a plurality of RAW image data transmitted from the communication unit A107. The frame rate of the moving image data 804 is 30 frames / second.
In FIG. 8, moving image data 805 is moving image data merged by the external apparatus 200 and recorded in the storage device 205. The frame rate of the moving image data 805 is 30 frames / second.

  According to the image data transmission method E21, the same RAW image data is transmitted twice from the communication unit A107 and the communication unit B108. Therefore, the CPU 111 adds recording designation information indicating either “target” or “non-target” to the additional information of each RAW image data output from the communication unit A 107 and the communication unit B 108. The recording designation information indicating “target” indicates RAW image data to be preferentially recorded or displayed on the external apparatus 200. The recording designation information indicating “not applicable” indicates that the RAW image data is not to be preferentially recorded or displayed on the external apparatus 200.

In the image data transmission method E21, the CPU 111 performs a process of adding recording designation information T1 indicating “target” to the additional information of each RAW image data output from the communication unit A107. In the image data transmission method E21, the CPU 111 performs a process of adding record designation information T2 indicating “not applicable” to the additional information of each RAW image data output from the communication unit B108.
When the merge recording function is ON, the recording control unit 204 of the external device 200 determines whether the recording designation information of each RAW image data is “target” or “non-target”. If the recording designation information of the RAW image data is “not applicable”, the recording control unit 204 controls not to record the RAW image data in the storage device 205. Thus, even when the same RAW image data is transmitted twice from the communication unit A 107 and the communication unit B 108, one of the two same RAW image data can be preferentially recorded in the external device 200. it can. As a result, it is possible to prevent the occurrence of the problem that the same RAW image data is recorded in the storage device 205 in duplicate.

Note that the image data transmission method E21 can be changed so that the recording designation information is added only to the additional information of the RAW image data output from the communication unit B108.
Thus, according to the image data transmission method E21, a plurality of RAW image data transmitted from the communication unit A107 can be preferentially recorded in the external device 200. Accordingly, even when the cable 301 is removed from the imaging device 100 or the external device 200 during transmission, the external device 200 can continue recording a plurality of RAW image data transmitted from the cable 300.

Note that the recording control unit 204 can detect duplicate RAW image data even when the content of the recording designation information is changed due to a transmission error or the like.
For example, as shown in FIG. 16, among the RAW image data transmitted via the cable 301, the recording designation information of the RAW image data whose time code information is “10: 00: 02: 00” is “target”. Consider the case of indicating “target” instead of “outside”. In this case, since RAW image data with time code information “10: 00: 26.0” is input from each of the cable 300 and the cable 301, the recording control unit 204 sets the time code information to “10: It can be determined that the RAW image data “00: 00: 26.0” overlap. In this case, since all of the two RAW image data whose time code information is “10: 00: 26.0” has the recording designation information indicating “target”, the recording control unit 204 sets the 2 One of the RAW image data is recorded in the storage device 205.

  For example, as shown in FIG. 17, among the RAW image data transmitted via the cable 300, the recording designation information of the RAW image data whose time code information is “10: 00: 02: 00” is included. Consider the case of indicating “not subject” instead of “subject”. In this case, since RAW image data with time code information “10: 00: 26.0” is input from each of the cable 300 and the cable 301, the recording control unit 204 sets the time code information to “10: It can be determined that the RAW image data “00: 00: 26.0” overlap. In this case, since all of the two RAW image data whose time code information is “10: 00: 26.0” has the recording designation information indicating “not applicable”, the recording control unit 204 One of the two raw image data is recorded in the storage device 205.
